Iyini i-hydroxypropyl methyl cellulose?

IHydroxypropyl methyl cellulose (HPMC), eyaziwa nangokuthi i-hydroxypropyl methylcellulose, i-cellulose hydroxypropyl methyl ether, i-cellulose, i-2-hydroxypropylmethyl ether, i-PROPYLENE GLYCOL ETER OF METHYLCELLULOSE, I-CAS No. I-HPMC ingahlukaniswa ngebanga lokwakha, ibanga lokudla kanye nebanga lezemithi ngokuya ngokusetshenziswa kwayo. Isetshenziswa kabanzi ekwakhiweni, ekudleni, emithini nasezimonyo, kumakhemikhali wansuku zonke nakwezinye izimboni.

Yiziphi ukusetshenziswa kwe-HPMC?

Imboni yezokwakha

1. Udaka lwamatshe
Ukuqinisa ukunamathela endaweni yamatshe kungathuthukisa ukugcinwa kwamanzi, ngaleyo ndlela kuthuthukise amandla odaka, futhi kuthuthukise ukuthambisa kanye nepulasitiki ukusiza ukusebenza kokwakha. Ukwakhiwa okulula konga isikhathi futhi kuthuthukisa ukusebenza kahle kwezindleko.
2. Imikhiqizo yeGypsum
Ingakwazi ukwandisa isikhathi sokusebenza sodaka futhi ikhiqize amandla aphezulu emishini ngesikhathi sokuqina. Ukugqoka okuphezulu kwekhwalithi ephezulu kwakhiwa ngokulawula ukungaguquguquki kodaka.
3. Upende ophuma emanzini kanye nesikhiphi sikapende
Ingandisa isikhathi seshelufu ngokuvimbela imvula eqinile, futhi inokuhambisana okuhle kakhulu nokuzinza okuphezulu kwebhayoloji. Izinga layo lokuhlakazeka liyashesha futhi akulula ukulihlanganisa, okuwusizo ukwenza lula inqubo yokuhlanganisa. Khiqiza izici zokugeleza ezinhle, kufaka phakathi isipatha esiphansi kanye nokulingana okuhle, qinisekisa ukuqedwa kahle kwendawo, futhi uvimbele ukuwohloka kopende. Thuthukisa i-viscosity yesikhiphi sikapende esisekelwe emanzini kanye nesikhiphi sikapende se-organic solvent, ukuze isikhiphi sikapende singaphumi sisuka endaweni yokusebenza.
4. I-Ceramic tile adhesive
Izithako zokuxuba ezomile kulula ukuzixuba futhi azihlanganisi, zonga isikhathi sokusebenza ngoba zisetshenziswa ngokushesha nangempumelelo, kuthuthukisa ukucutshungulwa nokunciphisa izindleko. Thuthukisa ukusebenza kahle kwamathayili futhi unikeze ukunamathela okuhle kakhulu ngokwelula isikhathi sokupholisa.
5. Izinto zokuzilinganisa phansi
Ihlinzeka nge-viscosity futhi ingasetshenziswa njengesengezo sokuqeda ukuxazulula ukusiza ukuthuthukisa ukusebenza kahle kwe-flooring. Ukulawula ukugcinwa kwamanzi kunganciphisa kakhulu imifantu kanye nokuncipha.
6. Ukukhiqizwa kwama-slabs okhonkolo akhiwe
Ithuthukisa ukucutshungulwa kwemikhiqizo ekhishwe, inamandla okubopha okuphezulu kanye nokuthambisa, futhi ithuthukisa amandla amanzi nokunamathela kwamashidi akhishiwe.
7. I-plate joint filler
IHydroxypropyl methyl cellulose inokugcinwa kwamanzi okuhle kakhulu, inganweba isikhathi sokupholisa, futhi ukuthambisa kwayo okuphezulu kwenza uhlelo lokusebenza lube bushelelezi. Ithuthukisa ngempumelelo ikhwalithi engaphezulu, inikeza ukuthungwa okubushelelezi futhi okulinganayo, futhi yenza indawo yokubopha iqine kakhulu.
8. I-gypsum esekelwe kusimende
Inokugcinwa kwamanzi aphezulu, yandisa isikhathi sokusebenza sodaka, futhi ingakwazi futhi ukulawula ukungena komoya, ngaleyo ndlela iqede imifantu emincane yokugqoka futhi yenza indawo ebushelelezi.

Imboni yokudla

1. I-citrus ekheniwe: ukuvimbela ukuba mhlophe nokuwohloka ngenxa yokubola kwe-citrus glycosides ngesikhathi sokugcinwa, ukuze kuzuzwe umphumela wokugcina.
2. Imikhiqizo yezithelo ezibandayo: yengezwa kujusi yezithelo neqhwa ukuze wenze ukunambitheka kube ngcono.
3. Isoso: isetshenziswa njenge-emulsion stabilizer noma i-thickener ye-sauce ne-tomato unama.
4. Ukugcotshwa kwamanzi abandayo kanye nokupholishwa: asetshenziselwa ukugcina izinhlanzi eziqandisiwe ukuze kuvinjelwe ukuguquguquka kwemibala kanye nokuwohloka kwekhwalithi. Ngemva kokumboza nokupholishwa nge-methyl cellulose noma i-hydroxypropyl methyl cellulose isisombululo samanzi, qhwaba phezu kongqimba lweqhwa.
5. I-Adhesive yamaphilisi: Njenge-adhesive yokubumba yamaphilisi nama-granules, inokuhle "ukugoqa ngasikhathi sinye" (ukuqedwa ngokushesha, ukugoqa kanye nokusabalalisa lapho uthatha).

Imboni yezemithi

1. I-Ecapsulation: I-ejenti ye-encapsulation yenziwa isixazululo se-solvent ephilayo noma isixazululo samanzi sokuphathwa kwethebhulethi, ikakhulukazi i-spray encapsulation yezinhlayiya ezilungisiwe.
2. I-ejenti yokuhlehlisa: 2-3 amagremu ngosuku, 1-2G ngesikhathi, izinsuku ezingu-4-5.
3. Isidakamizwa se-Ophthalmic: Njengoba ingcindezi ye-osmotic ye-methyl cellulose aqueous solution ifana neyezinyembezi, ayicasulanga kangako amehlo. Yengezwa emuthini we-ophthalmic njengesithambiso sokuthintana nelensi yamehlo.
4. Ijeli: Isetshenziswa njengesisekelo se-jelly njengomuthi wangaphandle noma amafutha okugcoba.
5. I-ejenti yokumithisa: isetshenziswa njenge-thickener kanye ne-ejenti egcina amanzi.

Imboni yezimonyo

1. I-Shampoo: Thuthukisa i-viscosity kanye nokuzinza kwebhamuza kwe-shampoo, i-washing agent kanye nesihlanzi.
2. I-toothpaste: thuthukisa i-fluidity ye-toothpaste.

Imboni yeziko

1. Izinto ze-elekthronikhi: njenge-adhesive eyakha umshini we-ceramic compactor kagesi kanye nozibuthe we-ferrite bauxite, ingasetshenziswa kanye ne-1.2-propanediol.
2. Umuthi ocwebezelayo: osetshenziswa njengomuthi ocwebezelayo wezitsha zobumba futhi uhlanganiswe nopende woqweqwe lwawo, ongathuthukisa ukubopha nokucutshungulwa.
3. I-Refractory mortar: Ingengezwa odakeni lwezitini eziphikisayo noma izinto ezifakwa esithandweni somlilo ukuze kuthuthukiswe ipulasitiki nokugcinwa kwamanzi.

Ezinye izimboni

I-HPMC iphinde isetshenziswe kabanzi ekwenzeni i-resin, i-petrochemical, i-ceramics, ukwenza iphepha, isikhumba, uyinki osekelwe emanzini, ugwayi nezinye izimboni. Isetshenziswa njenge-thickener, dispersant, binder, emulsifier kanye ne-stabilizer embonini yendwangu.

Ungalithola kanjani ngokubukeka izinga le-hydroxypropyl methyl cellulose (HPMC)?

1. I-Chromaticity: noma ingakwazi ukukhomba ngokuqondile ukuthi i-HPMC kulula yini ukuyisebenzisa, futhi uma i-ejenti emhlophe yengezwa ekukhiqizweni, ikhwalithi yayo izothinteka. Nokho, imikhiqizo yekhwalithi ephezulu isizothengwa.
2. Ukulunga: I-HPMC inamameshe angu-80 kanye namameshi angu-100 ngokuvamile, futhi amameshi angu-120 mancane. Ama-HPMC amaningi anamameshe angu-80. Ngokuvamile, inhlawulo ye-offside ingcono.
3. Ukudlulisa ukukhanya: beka i-hydroxypropyl methyl cellulose (I-HPMC) emanzini ukwenza i-colloid ebonakalayo, bese ubona ukudlulisa ukukhanya kwayo. Uma ukukhanya kukhudlwana, kungcono, okubonisa ukuthi kunento encane engancibiliki kuyo.
4. Amandla adonsela phansi aqondile: Lapho usinda kakhulu amandla adonsela phansi athile, kuba ngcono. Isilinganiso sibalulekile, ngokuvamile ngoba okuqukethwe kwe-hydroxypropyl kuphezulu. Uma okuqukethwe kwe-hydroxypropyl kuphezulu, ukugcinwa kwamanzi kungcono.
I-Hydroxypropyl methyl cellulose izinzile kuma-acids nezisekelo, futhi isisombululo sayo esinamanzi sizinzile kakhulu kububanzi be-pH=2~12. Singumkhiqizi ochwepheshe. Uma udinga lo mkhiqizo, ungaxhumana nathi. Yilokho kuphela okokwabelana kwe-HPMC kulolu daba. Ngethemba ukuthi ingakusiza uqonde i-HPMC.
